Specification of Letters Patent.

Application filed August 26.1907. Serial No. 390.131.

To all whom it may concern:

Be it known that I, JOHN H. Dons, a citizen of the United States of America, residing in Cherryvale, in the county of Montgomery and State of Kansas, have invented certain new and useful Improvements in the Method of Making Wrought Articles, of which the following is a full, clear, and exact description, reference being had to the accompanyingdrawing,forming part of this specification.

In making wrought articles such as steel rails and other sections of rolled metal there will be found in the center of the ingot, ,be-

fore it is passed through the rolls, an open and a more or less honey-comb portion commonly called the fpipe of the ingot. and when the articles are rolled asthe art is now practiced this pipe is onlyimperfectly're moved or destroyed because of its being surrounded by a morehomogeneous .or compact mass of metal, the result being an imperfect article.

The object of my invention isto overcome the above mentioned objection in making or rolling wrought articles such as steel or other metal rails or sections and'this I accomplih by castingthe ingot larger in cross'section than the desired or required size for passing through the. rolls (twice or four times as large) andthen splitting it longitudinally into two or four pieces so as to bring the pipe to the outside, the result being that when the ingot is passed through the rolls the pipe will be rolled out in the first few passes of the ingot through the rolls. I

In the accompanying drawings:. FigureI represents an ingot of twice the size desired lines show how it is split or. cut into two pieces to expose the-pi e to .the action of the rolls, Fig. 1-1 shows t e ingot of Fig Las it clearly bringing out or showing the pipe that exists in ingots. Fig. III represents an ingot the rolls, and the dotted lines show how it is split or-cut to bring the parts down to the desired size. tion to Fig. III that H doesto Fig. I.

B making rails according to my improved .met 0d the pipe is entirely removed from the finished article.

I claim:'

casting an ingot-of larger'cross section'than is necessa ting the ingot longitudinally through its pipe portion to expose the pipe of the ingot, and 'finally reducing the parts.
